    \[\sqrt{\frac{ 27 }{ 12 }} \implies \left( \frac{ 27 }{ 12 } \right)^{1/2} = \frac{ 27^{1/2} }{ 12^{1/2} }\]

    \[\implies \frac{ \sqrt{27} }{ \sqrt{12} } = \frac{ 3\sqrt{3} }{ 2\sqrt{3} }\]

    first step is to note that \[\frac{27}{12}=\frac{9}{4}\] then take teh square root of the top and bottom separately

    Should get used to the exponent rules

    \[\sqrt{\frac{27}{12}}=\sqrt{\frac{9\times3}{4\times3}}=\sqrt{\frac{9}{4}}=\frac{\sqrt{9}}{\sqrt{4}}=\frac{3}{2}\]

    forget the fractional exponents, they do not help your cause at all reduce first, take the square root last

    No, don't forget just know there's more then one way of doing it, and all you have to do is cancel out the sqrt(3)'s
